NPK 15-5-30 Potassium-Rich Fruit & Yield Blend

Overview

NPK 15-5-30 is a potassium-rich fertilizer blend formulated with a lower phosphorus share and a high proportion of potassium relative to nitrogen. Potassium plays a central role in fruit sizing, sugar accumulation, and overall crop quality, which makes this ratio a common choice during the reproductive and fruit-filling stages of a crop’s cycle. Because fruit and tuber quality is often assessed by buyers on arrival, this formulation is backed by the same batch testing and traceability described in our Certifications & Quality page.

When to Use It

This blend is well suited to fruit trees, grapes, and potatoes, where yield quality — not just vegetative bulk — is the priority. Growers often introduce this formulation as the crop transitions from vegetative growth into flowering, fruit set, and bulking stages, when demand for potassium typically increases relative to nitrogen.

Application Guidance

Because timing relative to crop stage matters for a potassium-heavy blend, buyers should align application windows with local crop calendars and soil/tissue test recommendations. As a general reference, growers commonly apply within the range noted above, concentrated around fruit development and pre-harvest periods rather than as a single early-season dose.
